Zip drive and AHA2910

[Matthew Kay]

Hi,

Has anyone had problems using an Iomega Zip drive and the AHA2910?
Actually, I have the 2910C. A Umax scanner (610S) and the zip  drive are
the only devices attached to the scsi card. A Promise UDMA EIDE card
controls the hard drives, and two EIDE/ATAPI cdroms are controlled by the
motherboard.

The scanner works like a charm but the zip drive constantly hangs. I can
read and write to the zip but at approxiametly every-other read/write the
zip drive will stop responding for 5 minutes or so. If I wait long enough
it will eventually finish the job. It appears that the driver is
attempting to reset the scsi device, gives up, then tries again. (If that
makes any sense.) I have included some data below.

I am wondering if maybe I should pass the following command to the
kernel: aic7xxx=no_reset

Any ideas?

Much thanks,
Matt
